you cant hide things forever... trust me, as you get more serious with her etc... its not going to happen... my wife is cool with me and how i am... im difficult as fuck with how i eat, work etc... but im loyal, im loving and i take damn good care of her and on top of that, we are best friends and when you have that, you take your significant other for how they are... if you have to go in and completely change into something your not, then that doesn't work... its one thing to change for the better but if this is what you want in your life, then its part of her life to and she needs to accept it bro...
